摘　　要：根据西藏某铜铅锌硫化矿矿石的性质,分别研究了磨矿粒度、捕收剂及工艺流程对浮选的影响。在磨矿粒度为-0.074mm占67.00%条件下,以乙黄药和乙硫氮的混合物为捕收剂,采用一粗一精两扫闭路浮选工艺流程,获得混合精矿中铜、铅、锌的品位分别为13.81%、16.74%、22.41%,回收率分别为95.47%、93.85%、94.04%。Integrated with ore properties, the effects of grinding fineness, collector agents and process flowsheet on the flotation of a copper-lead-zinc sulfide ore in Xizang were investigated, through which the processing parameters were determined. Adopting a closed-circuit flowsheet including one stage of roughing, one stage of cleaning and two stages of scavenging, with a grinding fineness of -0.074 mm range as around 67.00%, and using a combined collector of ethyl xanthate and diethyldithiocarbamate, a bulk concentrate with copper, lead and zinc grade of 13.81%, 16.74% and 22.41% respectively, and the corresponding recovery of 95.47%, 93.85% and 94.04%, respectively, was prepared.
